the marine and terrestrial regimes (Larsen et al., 2002;
Kristjánsdóttir et al., 2007; Gudmundsdóttir et al.,
2011a,b, 2012). For example, using palaeoceano-
graphic proxies and tephrochronological age models,
Knudsen et al. (2009) were able to reconstruct the
relative strength of Arctic and Atlantic water masses
on the North Iceland shelf throughout the last mil-
lennium. Foraminifera and diatom assemblages show
increased influence of Atlantic water masses during
the time interval ca. AD 800–1300 (the so-called Me-
dieval Warm Period or Medieval Climatic Anomaly),
whereas the interval ca. AD 1300–1910 (encompass-
ing the Little Ice Age) was characterized by decreased
